In the late 1970s, the development of Spring Drive began with the aim of harmoniously blending the traditional energy of a mainspring with state-of-the-art electronic watchmaking advancements. Inheriting this legacy of accuracy in watchmaking, Grand Seiko unveiled the Spring Drive Caliber 9RB2 at Watches and Wonders Geneva 2025. This groundbreaking movement receives the U.F.A. designation, which stands for “Ultra Fine Accuracy,” and boasts an astounding annual rate of ±20 seconds, making it the most accurate wristwatch movement powered by a mainspring today.
